Training, racing, and more. The Duro 1.5 is a svelte hydration companion perfect for training runs, long races, or streamlined days in the mountains. While it may be the smallest volume vest-pack in this series, it will carry you further than you ever imagined. With a body-hugging fit that provides bounce-free carry, smart and accessible organization for fuel and gear, and an included Hydraulics LT 1.5L reservoir that can be supplemented with soft flasks, the Duro 1.5 helps you focus on what matters most: continuous forward motion.

BUILT FOR SPEED

Vest-pack fit provides bounce-free stability and purpose-built for incredible comfort so you can focus on FKTs and PRs.

HYDRATION INCLUDED

Bottles, reservoirs, and add-on flexibility for short runs, long runs, and everything in between. You decide what you need. Duro/Dyna makes it possible.

EASY GEAR ACCESS

Pockets up front for quick access to fuel and soft flasks, trekking pole storage when you need to use your hands as much as your feet to move forward, and room for rain gear and extra layers.
